EDGAR PEOKI-IAM, OF NElV YORK, N. Y.

CAR-TRUCK.

SPECIFICATION forming part of Letters Patent No. 606,938, dated July 5, 1898.

Application filed February 5, 1897. Serial No. 622,192. (No model.)

supporting the car-body, and the trucks be-' ing equipped with double compound brakelever mechanism. The side frames of the truck are supported upon the j ournal-boxes by graduated spiral springs to cushion the motors and car-body and avoid pounding of the rail-joints. v

In the construction of the truck all the bearings and bolts are machine-fitted, and hot rivets are used in joining the several parts of the structure together. The truck as constructed has a short wheel-base, is strong and durable, and possesses superior easy-riding qualities.

The invention is illustrated in the accompanying drawings, which form part of this specification, and in which like features are indicated by like numerals ofreference in the several views.

In the drawings,-Figure lshows a plan of a truck embodying: my invention. Fig. 2 is a side e1evauon.- Fig. 3 is a longitudinal section on the line 8 3 of Fig. 1. Fig. 4 is a transverse section on the line 4 a of Fig. 1. Fig. 5 is an end view looking toward the left, Fig. 1.

Referring to the drawings, the side frames of the truck, both frames of which being in all respects exactly alike, comprise the pedestals or yokes 7, upper longitudinal beam 8, which is preferably duplex and which is connected to the yokes at about the center of their vertical height, and lower longitudinal beam 9, the beams 8 and 9 connecting the yokes together and riveted thereto, as shown, also the duplex end beams 10, riveted to the yokes, and the under truss-beams 11, riveted to the bottoms of the yokes and to said end beams, as shown.

The journahboxes are indicated at 12 and operate within the yokes in the usual manner. Between the tops of the journal-boxes 12 and the upper or top mernber of the pedestals 7 are plaoedgraduated spiral springs 13, there being recesses or apertures in the under surface of said upper members of the pedestals to reoeivethe springs 13 to prevent theiridisplacement. By this construction the side frames are spring-supported upon the journal-boxes, thus; cushioning the motors carried by the truck and also the car-bodies mounted on thefbolster of the truck. The pounding or hammering of the rail-joints is thus avoided. The axles of the truck are indicated at 14 and the wheels at 15.

Between the yokes of each side frame and below the tops of the pedestals there is arranged a half-elliptic spring 16, the ends of which seat,in suitableshoes 17, secured to the upper longitudinal beam 8, contiguous to the yokes. The springs 16 support'the bolster 18, the latter being connected to the springs in suitable manner and extending between saidsprings transversely of the truck and adapted to receive the car-body and be connected thereto. Connected to the bolster, near each end, just inside the half-elliptic springs, are cross-bars 10, through the ends of which pass the headed guide-bolts 20, the latter 'passingthrou'gh brackets 21, riveted to the upperlongitudinal beam 8, said guidebolts 20 being fixed in shoes riveted to the lower longitudinal beam 9. 'Bolts 20 and brackets 21 form appliances for preserving the proper, relative alinement of the bolster and the sidejbeams, the bolster being always.

held by said bolts and brackets in a vertical plane and at right angles to the side frames as well as to the springs 16.

From the described construction it will be seen that when the car-bod y is mounted on the truck the load is supported at the center or midway between the ends of the truck and that it is do ublc-cushioned on the truck-frame, first, by the half-elliptic springs supporting the bolster, and, secondly, by the spiral springs supporting the pedestals on'the journal-boxes.

In Fig. 1 a motor is shown at 22, supported in the .usual manner upon' Ithe aXle f-the truck and at the opposite side to the hanger 23, which is elastically suspended from the spring-equipped bolts 24,carried by the brackets or straps 25, riveted to the transverse beams 26, extending between the lower longitudinal beams 9 of the truck and being riv eted thereto.

At each end of the truckframe there is riveted to the end beams 10 an extension anglebeam 27, furnishing supports for the brake connections. The beams 27 are secured in position by extending the outer member 10 of the duplex end beam 10 around the beam 27 and riveting the two beams together, as shown in the drawings. The transverse beams 27 also afford strength to the truck structure. Secured to the transverse beams 27, near the ends thereof, are brackets 28,to which are pivoted links 29, which latter are pivotally connected to the brake-shoes 30, riveted to the brake-beams 31 in operative relation to the wheels of the truck.

At one end of the truck there are secured to the transverse beam 27 the brackets 32, which extend forward toward the center of the truck and furnish supports for the floating brake-bar 33 of the brake mechanism. Likewise secured to said beam 27 is the bracket 34, to which is pivoted the brake lever 35 as shown. The brake-lever 35 is also pivotally connected at 36 to the floating brake-bar 33, and to the outer end of said lever there is adapted to be connected the operating rod or chain 37.

Two upright levers 38, one at each side of the truck, are pivotally attached at their lower ends to the side frames. In the drawings these upright levers are shown supported by the side frames of the truck by rod 39, which extends transversely of the truck and is supported by brackets 40, riveted to the lower longitudina'l beams 9; but such levers may be supported directly on brackets riveted to said side beams 9, in which case the brake-rods and their connections to said upright levers and the brake-beams would be outside the truck-wheels and not inside, as shown in the drawings. 'To the upper ends of upright levers 38 are jointed brake-rods 41, whose opposite ends are jointed to the tloatingbrakebar 33; but the rods 41 may be omitted when levers 38 are attached near the end of the truck-frame. To the lower ends of the upright levers 38 are jointed the brake-rods 42, which at their outer ends are bifurcated and jointed to screw-bolts 43, which are connected to the brake-beam 31 by means of straps 44, riveted to said beam, the said screw-bolts passing through said straps, with nuts on each side of the strap, so that the rods 42 may be adjusted with relation to the brake-beam to suit conditions. Jointed to the upright levers 38, just above the point of connection of said levers with the side frame of the truck,there are jointed the brake-rods 45, which extend to the brake-beam 31 at the opposite end of the truck, being adjustably connected to said beam by the screw-bolt and strap connection employed for connecting brake-rod 42 to the brake-beam at the opposite end of the truck.

By the mechanism described the brakes are applied at both ends of the truck-frame simultaneously, as will be understood from an illspection of the drawings. A pull upon the rod or chain 37 will cause lever 35, which is fulcrumed to the floating brake-bar 33,to force said bar outward and at the same time through connecting-rods 41 move the upper ends of upright levers 38 in the same direction, with the effect of forcing the lower ends of said levers in the reverse direction, thus pulling on the brake-rods 42 and applying the brakeshoes at that end of the truck, the outward movement of the upper ends of the upright levers 3S applying the brake-shoes at the other end of the truck through means of the brakerods 45, connected to the brake-beam 31 at that end of the truck and jointed to the upright levers 38 above their pivotal connection on the truck-frame.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a car-truck the combination with the side frames including yokes or pedestals connected together by longitudinal beams, of half-elliptic springs mounted on said beams,
